ABSTRACT:
For the purpose of providing a two-phase asynchronous motor of the kind comprising a wound stator made up of two portions spacedly disposed parallel to each other and in which the flux flowing in all the field magnets of the stator is exclusively that of their own phase and in which sufficient space is available for a comparatively large number of field magnets, the stator windings of each phase are each accommodated in one said portion of the stator only and the poles of a member movable with respect to the stator are in the form of ferromagnetic bridges, surrounded and magnetically separated with respect to each other by a short-circuit element, the arrangement being such that the magnetic circuit of adjacent stator poles is completed directly via the pole shoes of the oppositely disposed portion of the stator. The invention is applicable to both linear and rotary motors. In the case of a rotary motor, the said member defines the rotor and the said element is in the form of a short-circuit cage.
